APT1211W

Overview

The Panasonic APT1211W is a Triac and SCR output optocoupler designed for AC switching applications. It features a Phototriac Coupler configuration with a DIP-4 package. Key electrical parameters include a maximum load voltage of 600V, a peak repetitive off-state current of 100mA, and a gate trigger voltage of 50V. The device provides galvanic isolation with a rating of 5000Vrms. It operates within a temperature range of -40°C to 100°C and supports through-hole PCB installation.

Feature Summary

• Provides high-voltage galvanic isolation between control circuits and AC loads
• Integrates an infrared LED emitter with a light-sensitive Triac output
• Designed for zero-crossing detection to minimize electromagnetic interference during switching

Applications

• AC motor speed control systems
• Solid-state relay modules
• Industrial process control interfaces
• Heater control circuits

Procurement Notes

Verify the specific suffix 'W' against the manufacturer's latest datasheet to confirm packaging variations or regional compliance differences. Ensure the procurement channel sources directly from authorized distributors to guarantee component authenticity and traceability. Cross-reference the part number with official Panasonic Electric Works documentation to confirm current production status and lead time requirements before finalizing orders.

Selection Notes

Select this component when high isolation voltage and low noise are required for AC load control. The 600V rating suits standard mains applications, while the 100mA output current limits suitability to low-power loads. Consider thermal management requirements given the operating temperature range. Verify that the control circuit can provide sufficient current to trigger the internal LED effectively within the specified voltage constraints.

Part Context

The APT1211W belongs to the APT series of solid-state relays and optocouplers manufactured by Panasonic Electric Works. This series focuses on reliable AC switching solutions using phototriac technology. The component serves as a critical interface in modern electronics, enabling safe control of high-voltage AC systems from low-voltage digital logic without direct electrical connection.
